Stellar chemical signatures of planet formation. Through demanding observations with the largest telescopes and extremely accurate analyses, the project will search for the characteristic fingerprints of planet formation imprinted in the chemical compositions of the sun and stars that we have discovered. The work will shed light on the origin of the solar system and identify stars harbouring planets.
Advanced simulation methods for the coupled solar interior and atmosphere. This project aims to develop numerical methods for complex magnetohydrodynamic simulations able to handle sharp and dynamically evolving inhomogeneities, spherical geometries, and dramatic variations in density and wave speed across the simulation domain. The project plans to develop these methods within the context of solar wave processes, which are fundamental to the transfer of energy from the sun’s interior to its out ....Advanced simulation methods for the coupled solar interior and atmosphere. This project aims to develop numerical methods for complex magnetohydrodynamic simulations able to handle sharp and dynamically evolving inhomogeneities, spherical geometries, and dramatic variations in density and wave speed across the simulation domain. The project plans to develop these methods within the context of solar wave processes, which are fundamental to the transfer of energy from the sun’s interior to its outer atmosphere, to the acceleration of the solar wind that rushes past the Earth continually, and to solar activity in general. This would provide the best available modelling of how the sun's atmosphere works, with direct implications for how the Earth's space environment is determined by solar storms and eruptions.Read moreRead less
Multi-region relaxation dynamics in fusion and stellar plasmas. This project aims to apply a static plasma modelling approach to linear modes of vibration and nonlinear explosive events in toroidally confined fusion plasma experiments and stellar atmospheres. The long-term survival of advanced civilisation depends on the development of reliable and ecologically sustainable energy sources. One of the most promising approaches for baseload electrical power is magnetic confinement fusion: harnessin ....Multi-region relaxation dynamics in fusion and stellar plasmas. This project aims to apply a static plasma modelling approach to linear modes of vibration and nonlinear explosive events in toroidally confined fusion plasma experiments and stellar atmospheres. The long-term survival of advanced civilisation depends on the development of reliable and ecologically sustainable energy sources. One of the most promising approaches for baseload electrical power is magnetic confinement fusion: harnessing, in a magnetic field, the nuclear reactions that power stars. This project will develop powerful new ways of modelling strong plasma instabilities in magnetised plasmas. Learning how to avoid these would remove a key barrier to fusion power.Read moreRead less
Seismology of solar and stellar magnetic activity. Seismic techniques for looking inside stars using observations of surface oscillations can be confused by the very surface magnetic fields that produce flares and other activity and that we wish to probe. This project will develop a new ray-based code, SunRay, which will be able to explore active regions taking full account of magnetic effects.
A Stress-relax Model for Stellar Flares. This project aims to improve our ability to predict solar and stellar flares by developing a theoretical model for the build-up and release of magnetic stress in stellar atmospheres. Solar flares are the most energetic events in the solar system, and together with associated coronal mass ejections can create hazardous conditions in our local space environment. Stellar flares are thousands of times more energetic and produce dangerous space weather for exo ....A Stress-relax Model for Stellar Flares. This project aims to improve our ability to predict solar and stellar flares by developing a theoretical model for the build-up and release of magnetic stress in stellar atmospheres. Solar flares are the most energetic events in the solar system, and together with associated coronal mass ejections can create hazardous conditions in our local space environment. Stellar flares are thousands of times more energetic and produce dangerous space weather for exoplanets orbiting flare stars. Expected outcomes include insight into the flare mechanism, and new approaches to flare prediction. The major potential benefit is improved solar and stellar space weather forecasting to protect human safety and infrastructure.Read moreRead less

Electrodynamics of magnetic explosions in astrophysics. The project aims to develop a new model for solar flares and pulsars that more realistically describes these phenomena. Solar flares and pulsars involve strong magnetic fields changing rapidly as a function of time, implying enormous inductive potentials. The project aims to show how the inductive field and the plasma response to it can be included in an electrodynamic theory. It plans to apply this theory to solar flares, and show how it c ....Electrodynamics of magnetic explosions in astrophysics. The project aims to develop a new model for solar flares and pulsars that more realistically describes these phenomena. Solar flares and pulsars involve strong magnetic fields changing rapidly as a function of time, implying enormous inductive potentials. The project aims to show how the inductive field and the plasma response to it can be included in an electrodynamic theory. It plans to apply this theory to solar flares, and show how it can resolve the long-standing ‘number problem’. It also plans to apply the model to pulsars, and show how the long-standing dichotomy between the vacuum-dipole and rotating-magnetosphere models can be resolved by synthesising them. The project intends to combine these ideas into a new model for the most extreme examples of magnetic explosions: superflares and giant bursts on magnetars.Read moreRead less
